(AHL) is a high-performance axial-terminal type resistor with flexible connections. These molded-construction aluminum-chassis resistors are available in higher power ratings than standard axial-terminal resistors and are better suited to withstanding vibration, shock and harsh environmental conditions.
(AHL) resistors are aluminum encased to maintain high stability during operation and to permit secure mounting to chassis surfaces. The metal housing also provides heat sinkable capabilities, allowing the units to exceed the power ratings.
The (AHL) Series is RoHS compliant and lead free. For non-standard technical requirements and custom special applications, please contact us for details with your specific needs.
